Detectives investigating the murder of journalist Lyra McKee in Northern Ireland have arrested four men.
The 29-year-old was shot dead in Derry while covering rioting in April 2019.
The men - aged 19, 20, 21 and 23 - were all arrested in the Derry area on Wednesday morning.

The PSNI say they are being held under terrorism legislation and have been taken to a Belfast police station to be interviewed.
Detective Superintendent Jason Murphy says: "These arrests are the culmination of a detailed two-year investigation into Lyra's murder and the events which preceeded it.
"The local community have supported the Police Service of Northern Ireland throughout the course of this protracted investigation , and I wish to thank them for their continued support and patience whilst this phase of the investigation is ongoing".
Detectives previously issued an appeal ahead of the one year anniversary of her death last year.
Letters were sent to people living in the Creggan area, directly appealing to them to think back to the events and bring any new information forward to police.
